Detailed Description

This class uses the ImageMagick++ libraries, to negate image (i.e. negative)

This produces a common negative effect popular in photography.

		long int	frame_number
	)

virtual

This method is required for all derived classes of EffectBase, and returns a modified openshot::Frame object.

The frame object is passed into this method, and a frame_number is passed in which tells the effect which settings to use from it's keyframes (starting at 1).
